## How to calculate specific heat

1. Determine whether you want to warm up the sample (give it some thermal energy) or cool it down (take some thermal energy away).
2. Insert the amount of energy supplied as a positive value. If you want to cool down the sample, insert the subtracted energy as a negative value. For example, say that we want to reduce the sample's thermal energy by 63,000 J. Then `Q = -63,000 J`.
3. Decide the temperature difference between the initial and final state of the sample and type it into the heat capacity calculator. If the sample is cooled down, the difference will be negative, and if warmed up - positive. Let's say we want to cool the sample down by 3 degrees. Then `ΔT = -3 K`. You can also go to advanced mode to type the initial and final values of temperature manually.
4. Determine the mass of the sample. We will assume `m = 5 kg`.
5. Calculate specific heat as `c = Q / (mΔT)`. In our example, it will be equal to `c = -63,000 J / (5 kg * -3 K) = 4,200 J/(kg·K)`. This is the typical heat capacity of water.
